The Rule is 10 seconds in NFHS, NCAA Men's/Women's, and NBA/WNBA, and 5 second in FIBA. That said in the 46 years I officiated (NFHS, NCAA Men's/Women's, and FIBA) I had only one situation where the Rule came into play (an AAU Girls', which play using NCAA Women's, qualifier to the National): When my count reached 12 seconds and she was still bouncing the Ball, I put air in my whistle. No more problems after that.
